molding material and which are provided with partitions and hingeportions formed integral with the receptacle parts during the moldingthereof.

In the drawing which shows a container or receptacle constructed inaccordance with this invention, and which illustrates but one of themany forms this invention may take,

Fig. 1 is a perspective view of a receptacle or container with the lidor cover in raised position;

Fig. 2 is a central vertical longitudinal section of the container ofFig. 1 with the lid in closed position;

Fig. 3 is a partial vertical longitudinal section .of the container ofFig. 1 with the lid closed, the section being taken at the hinge anddrawn to a larger scale;

Fig. 4 is a view similar to Fig. 3 showing a hinge of modifiedconstruction; and

Figs. 5 and 6 are partial views in rear and side elevation,respectively, showing a further modification of the hinge structure.

As shown in the drawing a receptacle or container constructed inaccordance with this invention comprises a lower or'base portion I-andan upper or cover portion 2, each molded as a unit of a suitable thermalsetting plastic molding material. The base portion I comprises-a bottom3 having a continuous peripheral flange 4 forming the sides and ends ofthe base portion and partitions 6 extending parallel to both the sidesand ends so as to divide the base portion into a plurality ofrectangular compartments,

the flange 4 and the partitions 6 being formed integral with the bottom3 during the molding of the base portion I. At directly opposite pointsthe flange 4 is formed during the molding thereof with outwardly openingrecesses 8 which form part of the hinges joining the cover 2 and base I.

The cover 2 comprises a top Ill having a continuous peripheral flange I2forming sides and ends thereof which overlap the sides and ends of thebase I and at points on the flange l2 corresponding to the recesses 8 inthe flange 4, the flange I2 is extended to form ears or hingeportions I!having inwardly projecting bosses or abutments I6 which interlock withthe recesses 8 and together therewith form hinges which secure the baseI and cover 2'together.

The projection'of the bosses or abutments I8 is small and the elasticityof the parts sufllclent to permit of the parts being separately formedand snapped together after the parts have fully set. While the recesses8 and abutments I6 cause the receptacle parts to interlock with themolds, the elasticity of the material is sufllcient to permit of theparts being readily removed from the molds.

In the structure shown in Fig. 4 the peripheral flange 20 of the basesection I is partly cut away on one side of the base section andadjacent each end of that side. At the cut-away portions the flange 28is thickened forming abutments 2| which extend from the bottom to thetop of the flange and reinforce the flange. The abutments 20 and theadjacent portions of the flange form,

the sides of openings which receive the'hlnge lugs 24 formed integralwith the peripheral flange 26 on the cover section 2. The hinge lugs 24are provided with hinge abutments 28 formed integral therewith whichengage in recesses 30 formed in the flange 20 of the base section i but.the abutments 28 and recesses 30 may be interextending along one sideof the base section I which portion is of substantially semi-cylindricalshape and projectsoutwardly beyond the remainder of the flange on thatside of the base section. The ends of the semi-cylindrical portion 32are flat and are recessed to receive abutments 33 on downwardlyextending lugs or ears 34 formed integral with fiat sections 35 whichclose the ends of a corresponding substantially semi-cylindrical portion36 of the peripheral flange 38 of the cover section 2. cylindricalportion 36 is of suflicient radius to pass outside of-the portion 32 ofthe flange 3| when the box or container is opened and is so positionedas to overlie the portion 32 when the box. is closed. I

The base sections I of the receptacles shown in Figs. .4, 5 and 6 willbe provided with partitions formed integral therewith during the moldingof the sections and the partitions may be arranged as shown in Fig. v1or in any other manner most; suitable for the purpose'to which thereceptacle is to be put.

A container or receptacle constructed in accordance with this inventioncan be readily made in ornamental colors and shaped or arranged forvarious uses or to receive various commodities and while particularshapes and arrangements have been shown it is to be understood the in-The semi- 15 a tom, a peripheral flange thereon, a projection of havingend walls provided with hinge abutments' adapted to enter the recessesin the ends of the projection on the base section.

2. In a container, a base section having a botsubstantiallysemi-cylindrical transverse Tcrosssection extending from said peripheralflange with the axis of said projection extending substantially parallelto said flange, said projection having flat end portions provided withrecesses to receive hinge abutments;- and a cover section having a top,a peripheral flange thereon, and a resilient projection extending fromthe peripheral flange of the cover section, said projection having ahollow portion overlying the substantially. semicylindrical projectionon the base section and having end walls provided with hinge abutmentsadapted to enter the recesses in the ends of the projection on the basesection.
